To read russian books on Aluratek
transform your .fb2 into .ebup with embedded russian fonts.
Use for instance online converter:

Best, regards,

PS
If you do not like the appearance of
produced .ebup
you may unzip it, change OPS/style.css
to what you want, and zip it again.
You may even use the fonts you like
from your computer (.otf, ttf will work for sure)
